Watching the webcast feels like being at some blockbuster movie premiere. There's a largish crowd following the launch and applauding on every launch stage completion.
Not that it's a bad thing per se, it's rather the opposite, it however, feels quite weird and staged as opposed to launches done by ESA, Roscosmos or even NASA.
ESA and Roscosmos launches are fairly sedate (almost fell asleep watching an Ariane 5 launch), but since the beginning launches managed by NASA have been pretty heavy with theatrics. Someone else mentioned JPL/Curiosity, which is one good example. Let's also not forget the massive cheering crowds at every Shuttle launch: https://youtu.be/OnoNITE-CLc?t=1m24s
The SpaceX hype is just a logical continuation of that, IMO.
